Or the speed cal as I have also heard that the 23t gear is a Jeep part and thereore some have had it wear excessively fast (few hundred miles) while others have been fine for many thousands of miles.

Due to the 5% off & the possibility of the gear wearing I decided to go with the speed cal myself. This will also allow me to correct my speedo should I ever change tire sizes.
